### Class

# Gio FilterOutputStream

#### Description [src]

    abstract class Gio.FilterOutputStream : Gio.OutputStream
    {
      GOutputStream* base_stream
    }

Base class for output stream implementations that perform some kind of filtering operation on a base stream. Typical examples of filtering operations are character set conversion, compression and byte order flipping.

#### Instance methods

###### g_filter_output_stream_get_base_stream

Gets the base stream for the filter stream.

###### g_filter_output_stream_get_close_base_stream

Returns whether the base stream will be closed when `stream` is closed.

###### g_filter_output_stream_set_close_base_stream

Sets whether the base stream will be closed when `stream` is closed.

###### Gio.FilterOutputStream:close-base-stream

Whether the base stream should be closed when the filter stream is closed.
